worked on license, client, and server
@ moved code into ChunkSystem from SimpleFS for managing
  the storage space of the block
+ reworked SimpleFS to contain only file operation methods
+ added initial implementation of file system functions
! fixed bug in server where filed 'fd' was used instead of 'mm'

This was a big change. It involved seperating the SimpleFS into
two seperate classes. This allows someone to build apon ChunkSystem
if they wished to give them some storage management.
